Journal of Public Economics, 158, 2018: 103-112

Providing international public goods is challenging due to the substantial asymmetries among nations; small-interest nations have strong incentives to ride cheaply. Our empirical results reveal cheap riding intentions in providing for climate change mitigation, a critical international public good. We propose the Cheap-Riding Efficient equilibrium to achieve Pareto optimality despite disparate cheap-riding incentives.

This effect is stronger for brands that tend to adopt others’ designs than innovative brands.
